Ok, a question for the more medically aware arrsers.
I can understand how the Pfizer mRNA vaccine works (a very simplistic description is that it delivers a harmless piece of genetic material into the body’s cells, and that genetic material causes the cells to create and release harmless covid-like genetic material (the spikes) that the body recognises as an invader, which the body then squishes).
What I don’t understand at the moment is what stops the body’s cells that are now producing the spikes from continuing to create the spikes.
Do spike-producing cells stop producing spikes once the initial fuel (for want of a better analogy) delivered by the vaccine runs out? Or does the body need to destroy both the “fuel” and the cells that the vaccine got to create the spikes?
